How many gallons of paint are needed for the outside walls of a building 26 ft high by 42 ft by 28 ft if they are 480 square feet. Of windows ? One gallon covers 400sq feet

The answer is 7.9 gallons of paint.

Step-by-step explanation:

According to the measurements of the building, it has two sides that have an area of 28x 26 = 728 square feet and two sides that have an area of 42 x 26 = 1092 square feet. Which means the total area of the building is (1092 + 728 ) x 2 = 3640 square feet. If 480 square feet of this area is windows, then the area to be painted is a total of 3160 square feet. If one gallon of paint covers 480 square feet, then the total amount of paint that is needed is 3160 / 400 = 7.9 gallons.

I hope this answer helps.
